ROBERT R. WEAVER, OF CHICAGO, ILLINOIS, ASSIGNOR TO GENERAL AMERICAN TANK CAR CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF 'WEST VIRGINIA.

T 0 all 10 710m it may concern 'Be it known that I,ROBERT R. WEAVER, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented a new and useful Improvement in Tank-Cars, of'which the following is a specification.

My invention relates, more particularly, to the means for securing the tank-portion of a tank car to the under-frame thereof whereby the tank is held on'the under-frame against displacement thereon and the tank is permitted to expand and contract under changes in temperature of the walls of the tank, without injury to the tank or the attaching means.

My primary object is to provide a novel, simple and inexpensive construction of tankanchorage functioning as above stated and which shall permit of the ready and convenient attaching of the tank to the underframe in the assembly of the tank therewith, and detaching of the tank therefrom as may be required in case of repair or replacement.

Referring to the accompanying drawings:

Figure 1 is a view in side elevation of a tank car embodying my invention, the car being shown somewhat diagrammatically. Fig. 2 is an enlarged sectiontaken at the line 2 on Figl and viewed in the direction of the arrow; and Fig. 3, a broken, enlarged, plan viewlof a portion of the under-frame and the anchor connecting the tank and under-frame together.

In the construction shown the underframe of the car is represented at 4', the bolsters at 5 and the wheeLequipped trucks at 6, all in accordance with common practice, the tank which extends lengthwise of the frame 4, being shown at 7-and its dome at 8.

The under-frame of the car is shown as involving the usual center-sill structure 9 formed of parallel angle-irons 1Ov spaced apartand extending lengthwise of the car, and acover-plate 11 surrounding the mem ber 10- and secured thereto preferably as hereinafter described.

V In accordance with my invention the tank 7 is securely anchored at one point by TANK-CAR.

Application filed July 1, 1921. Serial No. 481,744.

means which serve as a rigid connection between the tank and under-frame to prevent more especially, lengthwise movement of the tank and under-frame relative to each other,

while permitting of the lengthwise expansion and contraction of the tank relative to the under-frame, these means, which are shown as located midway of the ends of the tank but which may be secured anywhere along the tank as desired, comprising a seating member carried by the sill 9 and shown, by preference, as formed of two similar sectionslZ which extend lengthwise, of the members 10 and respectively surmount the latter. The sections 12 are preferably of the cross sectional shape shown, presenting the horizontal portions 13 at which they rest on the top of the cover-plate '11 being connected thereto and to the members 10, as by the rivets 14, passing through the portions '13, the cover plate 11 and the upper flanges of'the channels 10. Extending upwardly from the outer edges of the portions 18 are webs 15 with outwardly-directed saddle-forming portions 1.6 adapted to form a seat for the tank, the outer edges of the sections 1-3 terminating in depending flanges 17. The tank 7 has riveted thereto at 18 angle-irons 19, which are spaced apart a sufficient distance to fit with their depending flanges 20 flat'wise against the outer surfaces of the adjacent flanges 17, to which they are secured as by the rivets 21.

The anchorage means just'described thus rigidly holds the tank onthe under-frame and resists not only longitudinal movement of the under-frame and tank at this point, but also prevents vertical and lateral movement of theseparts relative to each other.

The under-frame at opposite sides of the anchorage in the construction shown is provided with saddles forming a support for the tank but relative to which the tank may shift lengthwise in expanding and contracting, these saddles, which may be of the construction commonly employed or of any other suitable construction, being shown at 22 at opposite sides of the anchorage.

To insure against lateral and vertical displacement of the ends of the tank and Y its ends, with the usual tank-bands represented at 23 which are connected at their opposite ends to the bolsters 5 and between their ends partially surround the tank, it being preferred that similar tank-bands, represented at 24, engage the tank at opposite sides of, and adjacent to, the dome 8, these bands being secured to the underframe in any suitable way, as for example in accordance with common practice, it being understood that the tank-bands referred to permit of lengthwise movement of the ends of the tank under expansion and contraction of the tank.

From the foregoing it will be readily un derstood that the tank may, with great facility, be attached to, and detached from, the under-frame. In attaching the tank, the tank is lowered onto the saddle-sections 12 to the portion shown and the rivets 21, or other fastening means, then applied to securing position, and thereafter the tankbands applied. In detaching the tank it will be noted, the rivets which penetrate the tank are not disturbed.

While I have illustrated and described a particular construction embodying my invention, I do not wish tobe limited thereto as various modifications and alterations may be made without departing from the spirit of my invention.

What I claim as new, and desire to secure by Letters Patent, is:

' 1. A tank-car comprising an under-frame,

a tank surmounting said frame, and an anchorage for preventing lengthwise movement of said tank and under-frame relative to each other at one portion of the tank formed of a seating member having depending flanges at the opposite sides of the center of the tank, the lower edges of said flanges being spaced from the structure beneath them, flanged members on the tank the flanges of which extend downwardly at the outer sides of the flanges on said seating member and means connecting adjacent ones of said flanges together, said tank bearing directly on said seating member between said flanged member.

2. A tank-car comprising an under-frame,

a tank surmounting said frame, and an anchoragefor preventing lengthwise movement of said tank and under-frame relative to each other at one portion of the tank formed of a seating'member made in sections located at ,oppositefsides of the center.

of the tank, each of said sections having a depending flange at its outer edge, the lower edges of which-arespaced from the struc-' ture beneath them, flanged members on the tank, the flanges of whichcextend downwardly at the outer sides of the'flanges on sand sections, and means connecting adja cent ones of said flanges together, said tank bearing directly on said seatingmemher between said members.

3. A tank-car comprising an under-frame, a tank surmounting said frame, and an an chorage for preventing lengthwise movement of said tank and under-frame relative to each other at one portion of the tank formed of a seating member having depending flanges at the'opposite sides of the center of the tank, the lower edges of said flanges being spaced from the structure beneath them, flangedmem'bers on the tank. the flanges of which extend downwardly at the outer sides of the flanges on said seating member, means connecting adjacent ones of said flanges together, andmeans engaging the free portion of the tank for preventing vertical and lateral displacement thereof beyond said anchorage means, said tank bearing directly on said seating member between said flanged members.

45.
